Well, I know part of this has been mentioned before but, I think I have
a new twist.

My mouse button is double clicking.
This was seen in Edit and Lightspeed C.
Well, this was disconcerting but I got a better one.

If I clicked in the scroll up box and if the mouse was not moved
(i.e. left in the box) the scrolling would continue until the top of the file
was reached.  YES, as if the mouse button was being held down.

Luckly I was far enough down into the file that I could observe the
actions.  To re-iterate:
Macintosh SE w/internal 20Meg. & standard keyboard
Using most recent *released* System and Finder (sorry numbers escape me)
I had no DAs active, no added FKEYs
I do have BeepInit31, SoundInit31 on and used Ramdomizer
In Lightspeed C v2 (upgrade v1 copy from Think)
Near the end of an edit file
Clicked once in scroll up box
Hands off mouse keyboard etc. 
Observed continuous scroll till top of file
Could not repeat it but did not try too many times

Note: I have no reason to assume that the mouse failed because all other
actions with the mouse acted normally.  I continued to use the machine
and had no effects occur as if the mouse button was stuck down.

Any help?  (Who's to point finger at? :-)
Note: am really only interested in a fix.
And am curious what the cause was.

SE mouse problems are actually in the mouse.  My mouse was double clicking
when it should have been single clicking (esp. when the button was depressed
slowly.)  I swapped mouses, the problem went away.  I moved my mouse to
another SE, the problem came back.  If you have troubles with your mouse
while it's still under warrantee, get it replaced.

I've noticed lately that I get double mouse clicks in the
vertical scroll bar in Finder windows.  I have a Mac+ that's
6 months old with System 3.2/ Finder 5.3.  I open a folder
in the Finder and click the vertical scroll bar to see
what's in the next part of the window.  The finder acts as
if the mouse were clicked twice, one click happens on the
downstroke of the mouse button and the second click happens
on the upstroke.  I have only noticed this in the Finder on
vertical scroll bars.  It happens about 2/3's of the time.

There is a hardware problem, I believe, with the debounce for the mouses.
I don't know if there is any cure, I'll check though...

As far as I've been able to figure out, the microswitch in the SE doesn't co-
operate nicely with the new plastic button. The switch will disengage before
the "click", and will sometimes remain engaged, probably due to the increased
friction from the welded plastic switch. The prolonged scroll mainly happens
when you rest your finger lightly on the mouse button (I do this all the time).

I have been told that my comments about the Macintosh SE mouse problems
were inappropriate.

Please disregard my comments on possible causes for SE mouse problems.

Thank you.
